Pomeroy Company, Inc.-, New York, N.Y., a corporation of New York Application June 11, 1954, Serial No. 436,191 6 Claims. {(315189-75) "standard in building operations involving large structures such as ofiice buildings and the like, the material of these metallic windows usually being steel. In recent times, lighter "metals such as aluminum have been found to be particularly well suited to building structures, and attempts have been made to form the conventional win- These attempts have not been entirely successful, and an object of the present invention is to provide a metallic window struc- "ture which is particularly susceptible of being manufactured "from the lighter metals such as aluminum.

A further object bf the invention is toiprovide "a window structure of the above character having elements capable of being formed by extruding operations.

Yet another object of the invention is to provide a metallic window structure of the above character wherein the jamb is of such structure that the basic components may be extruded and assembled quickly and easily by means of simple assembly techniques, the resulting structure aifording an effective and weather-tight metallic window.

These and further objects of the invention are accomplished by forming -a jamb from-side, inner and outer plates. Removably supported by the side plate intermediate the inner and outer plates is a bead defining a pair of parallel channels. Inadditi'on, channel closure plate means are associated with the bead to substantially enclose the parallel channels. Preferably, the various elements of the jamb are formed by extrusion from a lighter metal such as aluminum.

A further novel feature of the invention comprises the provision of flanges having 'curvedportions on the sash, such curved portions engaging'weather stripping suitably (positioned on the jamb and head, the resulting structure providing an effective and weather-tight metallic window.

These and further objects and advantages of the invention will be understood when the following description is read in connection with the accompanying drawings in which:

Figure 1 is a plan view of a metallic window structure formed in accordance with the present invention, this structure forming a conventional double hung window adjacent another partially illustrated window;

Figure 2 is a longitudinal section, considerably enlarged, taken on the view line 22 of Figure 1 looking in the direction of the arrows;

Patented June 30, 19 59 2 I "Figure 3 is a partial transverse section, greatly enjlar'ge'd, taken'on the view line 3-3 of Figure 1 looking in the direction of the arrows; and

Figure 4 is a view similar to Figure 3 illustrating a mullion structure in accordance with the present invent idn taken on the view line 44 of Figure 1 looking in the direction of the arrows.

Referring to an illustrative embodiment of the invention and particularly to Figure 1, an upper sash 1'0 and a lower sash 11 are slidably mounted in a conventional window frame formed by -a head 12, a sill 1'3, a'ndjambs 1'4 and 15 joining the ends thereof. The foregoing structure may be mounted in masonry '16 (Figures 2 and 3) in any conventional fashion such as by means of head strap hangers 17 and sill strap hangers 18, for example.

will be seen from Figure 3, the jamb 14 is formed with a side plate 19, an outer plate '20, and an inner plate 21, all formed integrally'as, for example, by means =df'extruding the metal in a conventional manner. A caulking fin 22 is provided with an angled leg 22a which is joined in any conventional manner such as by welding to the side plate 19. The fin 22 extends laterally from the plate 19 and cooperates with caulking compound 23 to seal the j'amb structure to the masonry 16. an order -to further strengthen the structure, side strap 'hangers :24, joined to the masonry 16 in any desired *m'anner, may be fastened to an angle iron 25 on the other side -of the side plate 19 'by means of rivets 26. Attached to the other leg of the angle iron '25 through *the ou'ter plate 20 by means of bolts 26 and nuts 26a are the window cleaning attachments 27. It will be apparent 'tha't added support will be afforded the window cleaning attachments by virtue of their direct-connection t'o the 'h'an'gers 24 through the angle iron 25.

The inner extremities of the outer and inner plates 2'0and'21 areformed with channels 28 and 29, respectively, within which are received weather strips 30 and 31, respectively. Preferably, the weather strips 30 and 31 are formed of shaped sheet metal having sufficient resilience to be normally urged inwardly towards the eentral longitudinal plane -of the jamb.

In the central plane of the jamb, a parting heard 32 an'd a wedge block 33 are provided, piling 34 extending firom either side of the wedge block 33 and engaging the upper and lower sashes 10 and 1 1. The wedge block 33 functions to fill the gap at the meeting rails when th'e upper and lower sashes are closed.

The parting head 32 is supported by a U-shaped snap bracket 35 for med by a pair of parallel plates 36 and 37 and a connecting member 38. Extending from each of the plates 36 and 37 is a pair of channel closure plates .39 and '40 extending obliquely up to the transverse plane of the inner extremity of the parting bead '32 and then extending parallel to the side plate :19 to lie in spaced relation to the adjacent edges of the outer and inner plates 20 and '21, respectively.

The U-shaped snap bracket 35 is slightly resilient and =forrned to snap on a further generally U-shaped supporting bracket 41 extending from and preferably formed Returning to the parting head 32, it will be seen that it is formed in a generally T-shaped section to provide channels 49 within which weather strips 50 are received, these weather strips being similar in form to the weather strips 30 and 31 and, in view of the manner in which they are mounted, it will be seen that the weather strips 50 normally urge their free sides outwardly away from the parting head 32.

The sash structure adapted to be used in connection with the jamb structure hereinabove described is illustrated in Figures 2 and 3 and includes the upper and lower sashes and 11, respectively. The sides of each of the sashes 10 and 11 are formed with outwardly extending flanges 51 and 52, the outer extremities of the flanges being formed with a curled or curved portion 53 within which the adjacent Weather strips 30, 31 and 50, respectively, are adapted to be received.

As is apparent from Figure 3, when the sashes 10 and 11 are in their normal positions, the flanges 51 and 52 cause the weather stripping to be somewhat compressed and as a result, the sashes and jamb are effectively sealed in all positions of the sashes. It will also be seen that due to the curved portions 53 of the flanges 51 and 52, small diflerences in sizes of the sashes 10 or 11 or of the jamb structure will not cause difliculty in their cooperation since some leeway is provided along such curved portions.

Referring to Figure 2, the meeting rails of the sashe 10 and 11 are sealed by means of a flange 54 adapted to be received Within a longitudinal pocket 55 within which weather stripping 56 is provided. Additional weather stripping 57 may be provided, if desired, to insure a tight joint between the sashes. The joint between the sill 13 and sash 11 is made weather tight by means of Weather stripping 58 and 59 carried by the bottom rail of the lower sash 11. The upper rail of the upper sash 10 is sealed to the head 12 by means of weather stripping 60 and 61 and cooperating elements which are shown in Figure 2, and the remaining portions of the sashes are formed in any desired fashion in accordance with conventional practices.

Turning to Figure 4, a mullion structure formed from jambs and 15a is illustrated, the jamb 15a being identical to the jamb 14 and the jamb 15 being slightly modified to provide a side plate 19:: with cooperating elements including a tongue 62 entering a slot 63, a flange 64 cooperating with an angled arm 65 and a flange 66 cooperating with a gasket 67, the jam-bs 1S and 15a being secured together by means of rivets 66a. In other respects, the companion parts of the mullion structure follow the window structure described above with respect to Figure 3.

From the foregoing, it will be seen that a window structure is provided that may be simply formed from extruded metallic sections which may be rapidly assembled. In addition, this structure provides for effective sealing between the sash and jamb under all conditions and regardless of small size variations in the manufacturing operations. The parting bead supporting structure may be easily snapped into position to provide an effective partition between the chambers within which the respective sash balances are housed. Furthermore, with the parting bead structure in position, these chambers or 4 channels are effectively enclosed by channel closure plates supported by the parting bead.

It will be apparent that while a metal has been referred to as the material from which the structure is formed, plastic material may serve satisfactorily in view of the facility with which it may be extruded.

It will be understood that the above-described embodiments of the invention are illustrative only and modifications thereof will occur to those skilled in the art. Therefore, the invention is not to be limited to the specific apparatus disclosed herein but is to be defined by the appended claims.
